This image of M27 was taken by ASV Astrophotographer Mark Sansom/\. M27 otherwise known as the The Dumbbell Nebula (also known as Apple Core Nebula or NGC 6853) is a planetary nebula in the constellation Vulpecula, at a distance of about 1227 light-years. This object was the first planetary nebula to be discovered; by Charles Messier in 1764. At its brightness of visual magnitude 7.5 and its diameter of about 8 arc-minutes, it is easily visible in binoculars and a popular observing target in amateur telescopes.
M36 is an open star cluster in the Auriga constellation, around 4100 light years from earth.
The cluster contains around 60 individual stars and spans roughly 14 light years across. Some of you might already have noticed a similarity with M45 (The Pleiades) and with good reason; the clusters are very alike in both layout and stars that make up the cluster. M36 just doesn't have the nebula that gives M45 that glow/halo. And of course, M36 is roughly 10 times further away, which also makes a visual difference.
This specific cluster is labelled as a Trumpler I,3,M cluster. Just like many other types of clusters (and objects in general); these are labelled based on specific characteristics. Lets dive into what it means exactly.
For starters, the scale is named after Robert Trumpler; an American astronomer recognized for his research towards all things related to star clusters. The first number in the classification ranges from I-IV; and is an indication of the cluster's core density (I being dense, IV being very scattered). The second number ranges from 1-3 and is quite simply an indication of how bright the cluster is (the higher the number, the brighter). The final letter can be either P,M or R; meaning "poor" "medium" or "rich" and is quite simply related to the number of stars in the cluster. P being less than 50, M between 50-100, R being more than 100.
At around apparent magnitude 6.3, this cluster is fairly easily visible for just about any telescope. Since it's fairly spread out (as open clusters tend to be); just make sure to use a somewhat higher field-of-view (not too much magnification).

The Moon orbits Earth at a speed of 2,288 miles per hour (3,683 kilometers per hour). During this time it travels a distance of 1,423,000 miles (2,290,000 kilometers). Follow @astronautluvgalaxy 👽👾🤖👽👾🤖

I seem to have spent most of my summer weekends dangling about on a #hangingbelay somewhere, and it's probably true, this time at #mothercareyskitchen . It's hard to capture the exposure and atmosphere at low tide in a #hangingbelayselfie - the boulders beneath @pocampo86 and I are as big as cars, even though it looks like we aren't that far off the ground. We'd worked harder than expected to earn a brief rest at the belay, the only place on P1 where you can fully shake out tired arms before committing horizontal moves under the roof towards the cleft leave you with nothing below your feet but churning water and burning forearms as you muscle up. I fought pretty hard on #deepspace , knowing we couldn't easily back off and that the tide would eventually start turning, but the fight is something that photos don't really show and words can't distill. Days like this are quite revealing - they show you what you're really made of when you're down to your last reserves of strength and cunning, what thoughts you have when you have so little left to give and how important it is to do hard things with a partner who will dig as deep and give it as much as you will. #tradclimbing#tradisrad#climbinggirls#girlswhoclimb#girlswholead#pembrokeshire#seacliffclimbing#womenonlead#adventure#climbingpartners#lastdaysofsummer
Something's Hiding in Our Outer Solar System, But It Might Not Be Planet Nine.
Somewhere in the outer reaches of the Solar System, beyond the orbit of Neptune, something wonky is happening. A few objects are orbiting differently from everything else, and we don't know why.
A popular hypothesis is that an unseen object called Planet Nine could be messing with these orbits; astronomers are avidly searching for this planet. But earlier this year physicists came up with an alternative explanation they think is more plausible.
Instead of one big object, the orbital wobblies could be caused by the combined gravitational force of a number of smaller Kuiper Belt or trans-Neptunian objects (TNOs). That's according to astrophysicists Antranik Sefilian of the University of Cambridge in the UK and Jihad Touma of the American University of Beirut in Lebanon.
The great Orion Nebula is a Diffuse Nebula around 1300 light years from earth. Visible to the naked eye even under light polluted skies, it is currently forming stars inside where gravity makes the gas collapse into young bright stars.. Hubble can view these stars actively forming!
Stayed up super late last night and saw Orion popping up over the neighbors house, decided to do a quick imaging session!
Was low in the sky and taken during last nights full moon but it still came out great to me :) can’t wait to improve on this object as I have all fall/winter to progress.

We ran a ground skirmish 4 vs 4. Two 890J's represented the objectives. The mission was to infiltrate the other 890, and take control to win. Had about 1500 meters in between. We won when I got in and stole it. My team killed the enemy team. The crimestat was worth it.

Here is the stunning image of ARP 273, arp is a pair of interacting galaxies, lying 300 million light years away in the constellation Andromeda. It was first described in the Atlas of Peculiar Galaxies, compiled by Halton Arp in 1966. The larger of the spiral galaxies, known as UGC 1810, is about five times more massive than the smaller galaxy. It has a disc that is tidally distorted into a rose-like shape by the gravitational pull of the companion galaxy below it, known as UGC 1813. The smaller galaxy shows distinct signs of active star formation at its nucleus, and "it is thought that the smaller galaxy has actually passed through the larger one ———————💫———————
There is also friction between the gas in the colliding galaxies, causing shock waves that can trigger some star formation in the galaxies. These processes can radically affect the galaxies. For example, two spiral galaxies can merge to form an elliptical galaxy, amazing 👽💫 #lightspeedracing#interstellar#astronaut#elonmusk#solarsystem#space#nasa#spacx#lightspeed#deepspace#elonmusk#planets#nebula#cosmos#earth#science#explore#stars#sun#moons
